Filed: 1984-06-13
Abstract: PURPOSE:To detect a surface potential accurately without any influence of fluctuation in source voltage by providing internally a means which stabilizes the output amplitude of a driving voltage to be supplied to a tuning fork to a tuning fork driving circuit. CONSTITUTION:A voltage appearing an electrode 12 has a voltage waveform depending upon the oscillation of the tuning fork and is received and amplified by an FET14, whose output voltage is passed through a capacitor 17 and amplified by the trailing-stage amplifying circuit; and the output is converted by the following rectifying and smoothing circuit 25 into a DC voltage, which is outputted. Therefore, the surface potential of a body to be measured appears at the electrode 12 as the voltage waveform and is amplified, rectified, and smoothed to output a DC voltage, which is detected. On the other hand, a limiter for voltage stabilization is inserted into the driving circuit for the tuning fork, so the amplitude of the tuning fork is stabilized without being affected by the fluctuation in source voltage and the voltage waveform appearing at the electrode is also stabilized, thereby detecting the accurate surface potential.
